Title: Plants for preheating and burning cement raw meal
IPC: F27B7/20
Filed: 1967-09-25
Abstract: In a plant for feeding powdered or granular material to a rotary kiln and having a preheater comprising several separators for solids from gases means is provided inside the kiln for hindering the flow of material through the kiln and for lifting it into the gases leaving the kiln. The lifting means takes the form of two annular walls 22, 23 spanned by lifters 24 to form compartments the material being carried to the top of the kiln 13 as the kiln rotates. In one form the material is fed in at 1 where it passes to a duct 4 leading to a separator 5, the latter receiving hot gases from a first separator 11. A dust precipitator 7 precedes a fan 8 delivering to exhaust or to a chimney. Solids from each separator and the precipitator are fed back to a previous stage by pipes 9, 12 or 28. In another embodiment (Fig. 3, not shown) a further separator 29 is provided, the pipe 32 of this construction delivers solid material to a duct 10 adjacent its entry to the kiln.

Patent ES-351928-A1 (ES)
Title: Volumetric dosing device
IPC: F17C13/02
Filed: 1968-03-23
Abstract: A volumetric filling device, in particular for filling vessels with a liquefied gas, e.g. butane or propane, up to a given level, operates when a can 6 moves upwardly to engage the undersurface of a base composed of two plates 1, 2 having a bore 10 in which is disposed a valve 19 and valve rod 18, a flexible diaphragm 25 being connected between the base and the rod 18 to form a liquid chamber closed by the valve 19 urged on to a sealing ring 12 by a spring 16. Liquid is supplied to the chamber through a flexible line 14 and when a can engages the base 1-2 to lift the device, an inflatable sealing gasket 8 engages the inner surface of the can. The whole device is raised until the sleeve 22 on rod 18 engages a stationary stop 24 such that as the device is raised further the ring 12 is lifted off valve 19 thus allowing liquid to flow into the can to fill the can up to the level of the sealing gasket 8, and air and any excess liquid is allowed to flow out through discharge line 20, 21. The can is lowered, thereby allowing spring 16 to assert itself to stop the flow. An automatic rotary machine having such filling devices is described, Fig. 5 (not shown). In a modification, Fig. 6, liquid is supplied to the chamber 77 through a flexible line 78 connected with the valve rod 18. The base 70, 71 is integral with a casing 79 which surrounds a flexible spring 80 connected between the casing 79 and a cup-like member 81 integral with rod 18 and connected with the rod by a nut 83. The flexible line 78 is slidable in a sleeve 82 which acts as a stop for the bolt 83. A can lifts the device as a whole against the action of springs 75, the valve 19 being held on its seat by spring 80 and the differential effect of hydraulic pressure. When nut 83 is brought to a stop by sleeve 82 the rest of the device continues its upward movement until casing 79 comes up against plate 76 thus opening valve 19 and allowing liquid to flow into the can. When the can fills to the level of the valve, air and excess liquid flows through discharge tube 85, 86, 87 and thus into the inlet 88 of an adjacent filling device. Tube 85 is of small section such that the pressure builds up in the can and chamber 77 causing the valve to be closed by differential pressure.

Title: Inversion layer field effect device with azimuthally dependent carrier mobility
IPC: H01L29/78
Filed: 1968-11-06
Abstract: A two-dimensional conduction layer in an insulated gate field-effect semi-conductor device lies parallel to a crystallographic plane exhibiting azimuthally dependent carrier mobility. In the embodiment a pair of series-connected MOSFET'S Q 1 , Q 2 forming an inverter circuit are built into the face of an N-type Si wafer lying in a 110 crystallographic plane. The drive transistor Q 1 is arranged with its channel along the 110 direction, that of maximum hole mobility, while the channel of load transistor Q 2 lies along the 001 direction for minimum mobility and hence highest impedance for a given size of device. The P-type source 20 of Q 1 drain 34 of Q 2 and the region which forms and interconnects the drain of Q 1 and source of Q 2 are diffused regions and the gate insulation is constituted by thinned areas of an overall thermal oxide film. Use of germanium, A III B V and A II B VI compounds instead of silicon is contemplated. A MOSFET with additional Hall electrodes for making mobility measurements is also described (Fig. 1, not shown).

Title: Improvements in brush holding arrangements in dynamoelectric machines
IPC: H01R39/38
Filed: 1969-06-17
Abstract: A brush assembly in a dynamo-electric machine comprises a prestressed volute spring 24 secured to a rigid backing member 26 which is pivotally mounted (36) on the brush holder so that the spring both urges the brush 16 towards the current-collecting surface 18 and at the same time biases a portion 42 of the backing member against the brush to hold the brush against a surface 44 of the brush holder. The spring preferably engages a sloping surface 30 of the brush so that the brush is held against surface 44 at both its upper and lower ends. The backing member 26 has a handle 48 to facilitate the disengaging of member 26 from pivot 36 when the brush is to be changed, complete removal of the member being prevented by pin 50. The surface of the portion 42 of the backing member may have a friction-free coating. The brush assembly may be used with reversible machines and may be mounted obliquely relative to the currentcollecting surface 18.

Title: Core removal apparatus
IPC: B29C67/00
Filed: 1976-01-29
Abstract: The present invention discloses an apparatus for removing a multi-section core from a vehicle tire and the apparatus includes a frame which pivotally mounts a support table so the support table can be moved between a first position, in which it is generally horizontal, to a second position, in which it is at an acute angle to the horizontal. The support table carries roller means which are adapted to engage a sidewall of and rotatably support a tire in a position with the axis of the tire generally at a right angle to the support table. A core clamp is positioned within the circumferential confines of the tire when it is supported by the rollers in the horizontal position of the support table and the core clamp is adapted to move between first and second longitudinal positions. The core clamp has jaws thereon, which are adapted to move between open and closed positions to grasp a selected section of a multi-section core and longitudinal movement of the core clamp causes the selected section of the core to be pulled from the tire in a direction generally parallel to the support table and in a diametral direction in relation to the tire. A backup support is provided for engaging a portion of the tread area of the tire to prevent movement of the tire when the core clamp is removing a core section from the tire. A rotatable spindle, which is movable between first and second positions, is provided to engage a portion of the tread area of the tire at a position generally diametrically opposed from the backup support. The spindle rotates the tire to desired rotational positions to properly position the various core sections so they can be engaged by the jaws of the core clamp. Motive power means are provided in the apparatus to cause all of the aforementioned movements and to cause rotation of the spindle.

Title: Insulated vessels for low temperature liquids - have cast or injected foam filling between elastic joints
IPC: F17C13/00
Filed: 1977-06-08
Abstract: An insulation system for vessels contg. fluids at very low temp. such as liquefied gases, uses synthetic foam plates, the edges of which have expansion joints of synthetic material, and allows some play between the surface of the vessel and the insulation. The insulation is produced by a) applying a slide surface coating to the wall of the vessel, b) fitting a gril arrangement to the vessel consisting of bars spaced out on or round the walls of the vessel, c) filling in the spaced between the bars with injected polyurethane foam, d) applying a coating on to the surface of the insulation. The foam may be reinforced and may be covered over by a metal cladding, whilst alternatively, the foam may be generated in situ. The bars of the grill are glued to the surface and arranged so that their crossing are alternately vertical and horizontal, continuous or interrupted. Where the bars cross they are not glued but are filled in with foam. Expensive assembly methods are eliminated, and temp. movements between the vessel and the insulation are evened out.
